Abstract

The increasing demand for environmentally friendly construction materials has encouraged the use of industrial and organic waste, such as fly ash and coconut fiber, as alternative additives in paving block production. This study aims to evaluate the effects of using fly ash as a partial cement replacement and coconut fiber as an additive on the mechanical strength and environmental aspects of paving blocks. The research method is experimental, based on SNI 03-0691-1996 and ASTM C109/C109M-21 standards. The mix variations consisted of 0%, 10%, 15%, and 20% fly ash, with an addition of 2% coconut fiber, using two curing methods: room temperature and water immersion. The compressive strength test results at 28 days showed that room temperature curing produced values of 11.07 MPa, 11.58 MPa, 12.85 MPa, and 12.06 MPa, respectively. Meanwhile, water immersion curing yielded 14.40 MPa, 14.89 MPa, 16.13 MPa, and 15.69 MPa. The highest flexural strength, 4.25 MPa, was achieved with a mixture of 10% fly ash and 2% coconut fiber cured by water immersion. The use of fly ash and coconut fiber not only enhances the mechanical strength of paving blocks but also contributes to reducing industrial and agricultural waste. This combination has proven effective in improving material performance while supporting sustainable development as an eco-friendly solution

Abstract

The increasing demand for environmentally friendly infrastructure has encouraged innovation in construction materials that can reduce carbon emissions. One of the efforts undertaken is the utilization of industrial by-products such as fly ash and Ground Granulated Blast Furnace Slag (GGBS) as partial substitutes for cement in the production of paving blocks. This study aims to investigate the effect of varying fly ash and GGBS mixtures on the compressive and flexural strength of paving blocks, as well as to determine the optimal mixture proportion that meets structural strength standards for pavement applications, particularly in heavy vehicle parking areas. The experimental method employed four mixture variations of fly ash and GGBS in a 1:1 ratio, namely 0%, 7.5%, 15%, and 25% of the cement weight. Compressive strength tests were conducted at curing ages of 7, 14, and 28 days, while flexural strength tests were performed at 28 days. The results showed that the mixture containing 85% cement, 7.5% fly ash, and 7.5% GGBS achieved the highest compressive and flexural strength values, 21.5 MPa and 4.3 MPa, respectively. These values meet the quality requirements of Grade B as specified in SNI 03-0691-1996, indicating that the paving blocks are suitable for use in heavy vehicle parking areas. The findings demonstrate that the appropriate incorporation of fly ash and GGBS not only enhances the mechanical performance of paving blocks but also contributes to reducing cement consumption and carbon emissions. Thus, this research provides a significant contribution to the development of more sustainable.
